IMPROVEMENT IN JOURNAL-BOXES.

Specification forming part of Letters Patent No. 139,287, dated May 27, 1873; application filed February 15, 1873.

To all whom it may concern Be it known that I, JOHN A. ALTHOUSE, of New Harmony, in the county of Posey and State" of Indiana, have invented a new and useful Improvement in J ournal-Boxes, of

which the following is a specification:

This invention relates to the construction of journal-boxes for shafting and similar purposes; and consists in the mode of tightening the box to the journal when, from wear or other cause,

a it has become loose.

. Figural is a sectional side view of the box, the section being on the line a 00 of Fig. 2. Fig. 2 is a sectional top view, the section being i '-taken on the lineyy of Fig. 1. Fig. 3 is a 1 with the back of each section recessed or cut away, as seen in Fig. 2,with flanges F F, which fit onto the ends G of the pillowblock, and with the projecting lips H H, which inclose and hold the adjusting-screw I. The back side of the section is out on an incline. J is a movable block, with inclined face, to which theadj listing-screw I is attached. K is a col;

lar on the screw. The block J is allowed play up and down; and the inclined surfaces of the section and block being reversed and placed in contact with each other, and the screw stationary longitudinally, it will be seen that, as the screw is turned, theblock will be moved up or down, according to the direction the screw is turned, and will act as a wedge, In this case, the section is forced toward the journal when the block is forced down. These side sections cover each about one-third of the diameter of the journal,

and receive the side thrust caused by horizon tal belts from the shaft or other side pressure on the journal. The adjusting-screws I extend up through the cap of the box, as seen in Pig. 1, so that the sections can be set up to the journal and take up any play while the journal is in motion, if desired. The resistance of the movable blocks is against the vertical ends G G of the pillow-block, which ends are stationary. By this arrangement the box is made to tit the journal at all times in the mostsim; ple and efi'ective manner.

Having thus. described my invention, I

claim as new and desire to secure by Letters Patent- The sides 0 D, provided with flanges F F,

'lips H H, and inclined edges, combined with screw I, inclined blocks J, and pillow-block G,

as and for the purpose described.
